Application filed April 8,. 1915. Serial No. 19,609.

To all whom it may concern:

it known that I, FRANK L. Fos'rnn, a citizen of the United States, and a resident of Cleveland. county of Cuyahoga, State of Ohio, have invented certain new and useful improvements Composite Roofing, of which the following is a specification.

This invention relates to roofing and particularly to the type of roofing which is built into the building itself and comprises a continimus structure, as contrasted with roofs which comprise separate elements or sections which are previously preoared and positioned adjacent one another to form a roof having well defined joints between the sections thereof.

One object of my invention is to provide a roof havin T a gutter, which roof comprises a masonry foundation that may be monolithic or that may be built up of tiles, slabs, etc, laid in cement, and supporting a weatherproof and fireproof coating.

Another object of my invention is to so arrange the elements of the weatherand fireproof coating of a roof with relation to the gutter formed in the masonry foundation element thereof that said elements will extend in the direction of the flow of water in said gutter, whereby an unobstructed flow 'is assured and the possibility of water dostroying joints between elements is avoided.

Another object is to so arrange weather and fireproofing elements of a roof with relation to a masonry foundation element thereof having a gutter that a durable gutter covering will he formed, which will be connected to a weatherand fireproof coveringof the water-shed of the roof in a manbe formed of concrete or of tiles, etc, laid so H1 cement. The drawings illustrate a roof 1 made of concrete, having a gutter2 formed by a horizontal section 3 of the roof and an upwardly-extending. wallsection The roof foundation being of masonry, it is a necessary that a priming or filling material 5 be applied thereto to enter into the pores and thereby attach itself to the foundation and, at the same time, provide a surface to which weatherproof material will adhere. 7

On top of the filling or priming material 5,

preferably after it has dried or hardened,

is placed a comparatively heavy coat 6 of asphalt which has been heated so that it may be spread with a mop or in some well- I known manner. The heat of this coating when' it is applied causes it to adhere to. the coating 5, which may be asphalt or any material which will serve the purposes hereinabove stated. These two coatings 5 and -6 cover the watershed of the roof, as well as the surface of the gutter, including the wall forming a part thereof. Longitudinally of the gutter there is now laid upon the hot coating 6 a strip 7 of asphalt-saw 35 rated asbestos felt. This is rolled into the coating 5 while it is still hot, so that it be-' comes firmly attached thereto. 'Jlhesur faceof this layer is then'moppecl with a coating 8 of asphalt, which is heated up so that it'may be spread by a mop. Qn top of this coating 8 there is applied a strip 9 of asphalt-saturated asbestos felt, which is wider than the strip 7, and which fits into the gutter, covering the wall and the bottom thereof, and it is rolled down onto the layer 8 of asphalt before that asphalt is cooled, so that this layer of felt is firnily attached to the roof. This layer is then mopped with a coating of asphalt '10,.and,

while this coating is still hot, another layer 11 of felt is placed on it, which layer is wider than the layer 9. This layer 11 is in turn mopped with a coating of asphalt 12, and a layer 13 of felt is rolled into it while it is still hot. The surface of this layer is then mopped with a final layer of asphalt 13. The layer 13 of felt is preferably the widest of hose forming the covering er the gutter. Additional ne atin- 1'10
